This tutorial is applicable to Audi A4-A5 models from 2017-2024, enhancing the ambient atmosphere
1. Do not install privately if you are not a professional, to avoid damage to the machine and other accidents.
2. Before installation, check whether all vehicle functions are normal and if there are any scratches on the interior surfaces. If there are issues, report them to the customer promptly.
3. Before disassembling the vehicle, installers should remove all metal items and other hard objects on their person to prevent damage to the car seats or interior during disassembly.
4. During installation, ensure that removed vehicle components are placed properly to avoid scratching the dashboard. Clean up any debris left during wiring promptly and do not leave it inside the car. Ensure proper insulation of wire connections to prevent short circuits.
5. Wiring should be reasonable; the installation space inside the car is limited, so minimize occupied space to facilitate main unit installation. Plan the main unit connection lines well. Avoid routing wires in a way that affects movable vehicle parts, such as the steering column shaft, accelerator and brake pedals, and other vehicle control components. After wiring is complete, secure the harness to prevent detachment.
6. Do not plug or unplug connected accessories while the system is powered on, to avoid hot-plugging damage to the main unit or accessories
